Description OSIDB Bzimport 2025-07-10 09:02:15 UTC 
In the Linux kernel, the following vulnerability has been resolved:

eth: fbnic: avoid double free when failing to DMA-map FW msg

The semantics are that caller of fbnic_mbx_map_msg() retains
the ownership of the message on error. All existing callers
dutifully free the page.
